How does El Niño affect north america?

Question

Samuel Albin · Accepted Answer

El Niño is a term used for the period when sea surface temperatures are above normal off the southern American coast along the equatorial Pacific.

El Niño causes the jet stream in the southern US to shift from west to east, increasing the area's susceptibility to severe weather events. Generally speaking, El Niño brings: Over the winter, El Niño typically reduces the amount of snowfall in central parts of the US states; warmer-than-normal temperatures invade northern latitudes of Canada, Alaska, and the northern tier of US states; the Gulf coast of the US experiences below-normal temperatures. For North America, the storm track is shifted, resulting in an increase in precipitation along the southern tier of the US and Mexico. El Niño typically has a negative impact on the Atlantic hurricane season and a positive impact on the tornado season, with the latter occurring later in the year after the event begins.

undefined El Niño can affect North America by causing warmer and drier conditions in the northern part of the continent, leading to increased risk of drought, heatwaves, and wildfires. It may also bring more precipitation to the southern parts, resulting in increased rainfall and potential flooding. El Niño can influence weather patterns, impacting agriculture, water resources, and overall climate conditions in North America.
